Lanthanide-induced shift reagents enable the structural elucidation of natural products in inseparable complex mixtures – the case of elemenal from Inula helenium L. (Asteraceae)

Abstract

A new approach to the structural elucidation of constituent(s) of complex mixtures was developed based on the use of lanthanide-induced shift reagents. This methodology was successfully applied in the identification of a rare sesquiterpene elemenal.
